Upgrade to c-kzg 2.1.0 and alloy-primitives 1.0 (#7271)

Browse Source 
Update `c-kzg` from `v1` to `v2`. My motivation here is that `alloy-consensus` now uses `c-kzg` in `v2` and this results in a conflict when using lighthouse in combination with latest alloy. I tried also to disable the `czkg` feature in alloy, but the conflict persisted.

See here for the alloy update to `c-kzg v2`:  https://github.com/alloy-rs/alloy/pull/2240

Error:
```
error: failed to select a version for `c-kzg`.
...
versions that meet the requirements `^1` are: 1.0.3, 1.0.2, 1.0.0

the package `c-kzg` links to the native library `ckzg`, but it conflicts with a previous package which links to `ckzg` as well:
package `c-kzg v2.1.0`
... which satisfies dependency `c-kzg = "^2.1"` of package `alloy-consensus v0.13.0`
... which satisfies dependency `alloy-consensus = "^0.13.0"` of package ...
...
```


  - Upgrade `alloy-consensus` to `0.14.0` and disable all default features
- Upgrade `c-kzg` to `v2.1.0`
- Upgrade `alloy-primitives` to `1.0.0`
- Adapt the code to the new API `c-kzg`
- There is now `NO_PRECOMPUTE` as my understand from https://github.com/ethereum/c-kzg-4844/pull/545/files we should use `0` here as `new_from_trusted_setup_no_precomp` does not precomp. But maybe it is misleading. For all other places I used `RECOMMENDED_PRECOMP_WIDTH` because `8` is matching the recommendation.
- `BYTES_PER_G1_POINT` and `BYTES_PER_G2_POINT` are no longer public in `c-kzg`
- I adapted two tests that checking for the `Attestation`  bitfield size. But I could not pinpoint to what has changed and why now 8 bytes less. I would be happy about any hint, and if this is correct. I found related a PR here: https://github.com/sigp/lighthouse/pull/6915
- Use same fields names, in json, as well as `c-kzg` and `rust_eth_kzg` for `g1_monomial`, `g1_lagrange`, and `g2_monomial`
